VALVE.

Specification of Letters Patent. v )Patented Aug. 22, 1916.

Application led September 17, 1915. Serial No. 51,204.

To all whom t may concern.:

` Be it known that I, LAWRENCE EMERY CANNING, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, `have invented certai-n new and useful Improvements in Valves, of which the following is a specification. l

My invention primarily has for its object to provide a new and improved form of valve, more particularly of that type utilized as basin cocks, bathtub cocks, curb stops, etc., of a simple and economical construction and in which the several parts are especially so designed that no cuttings or dirt can pass Aby or under any ofthe washers, and the valve therebyadapted to grind itself.

With other objects 'in view that will hereinafter appear, my invention embodies the peculiar construction and novel arrangement of parts that constitute my improved valve, all .of which will be hereinafter fully explained, specically pointed out in the appended claims and illustrated in the accompanying drawings, in which:

Figure l is a vertical longitudinal section of a valve that embodies my invention. Fig. 2 is a transverse section thereof on the line 2-2 on Fig. 1. Fig. 3 is a detail View, the several parts of my improved valve being shown in longitudinal section and separated from each other. Fig. 4 isa perspective view showing the packing washers separated. Fig. 5 is a vertical longitudinal section of a modified form of my valve. Fig. 6 is a cross section on the line 6 6 of Fig. 5. Fig. 7 is a detail ltransverse section of the ball and a portion of the turning key. Fig. 8 isa sectional perspective of the plunger which seats against the aforesaid ball. Fig. 9 is a detail perspective of the faucet nozzle showing the; ball valve seat. Fig. 10 is a vertical longitudinal section of a further modification of faucet construction.v Fig. 11-

/is a transverse section on the line 11-11 on Fig. 10`parts being, however, in elevation;

lIn the accompanying drawings, I have illustrated my invention in the nature of an.

ordinary spigot or faucet, and the said and preferred form, which is illustrated fully in= Figs. 1, 2 and 3 embodies a shell casing l, which includes a stepped bearing lO and an internally threaded flange 11 and an internally threaded inlet extension or neck 12.

2 designates a ball or globe valve provided with the usual waterpassage 20, stem 21 and with a foot portion 21a for engaging the stepped bearing 10. The valve stem has a i 'collar 22, the purpose of which will presently appear, and the said stem 21 connects' ,portion 30 that fits into the threaded flange 11, and includes an externally threaded boss 31 to receive the nut 4 which forms a packing gland, as is clearly shown in Fig. l, by reference to which it will also be seen the member 3 has a socket 32 that fits over and down against the collar 22 on the valve stem and thereby securely holds the valve down 1n proper position within the casing or shell 1.

5 designates what I term a tubular plunger or piston device,oand the said device fits within the extension or neck 12 of the casing 1 and it includes a dished head 50 that seats against the ball valve 2. Plunger 5 also includes a reduced portion or stem 51 that forms a seat for a stout coiled spring G that normally forces the plunger head in a Itight frictional contact with the ball valve.

7 designates a tubular coupling member, whose inner end 7l is externally threaded to screw into the internal threads 72 of the inlet external thread 55 on the outer end for receiving a holding nut 9 that engages and holds a pair of rubber washers 91-92 separated by a disk washer 93 all mounted on the extension 54. The washers 91 and 92 assist in retaining the spring 6 in place with thc inner end thereof resting against the shoulder formed by the end 7l of the couplingl 7, as is best shown in Fig. 1. The outermost one 91 of the washers is in the nature of a cup washer, since that end against which the lincoming water flows is dislred, as indicated, by 91a, it being understood that the impact of the entering water on the cup washer tends to assist the spring 6,- under increased tension, to force or shove up the plunger headV to seat against valve 1.

` While I have shown two washers 91-92 separated by the ,disk 93, mounted on the plunger portion 54, such arrangement of washers being preferred, since the first or cup shaped washer 9, acts to protect the washer 92, but a single 011e of such washers may be used in place of the two washers and the separating disk, (see Fig. l). Y

. By reason of the peculiar construction and novel arrangement of the parts described and illustrated in the drawings, the ball valve when in use is caused to grind itself, for the reason that no dirt or cuttings can pass under or cut the washers, this being readily understood when it is considered that the impact of the water against the cup washer tends to expand the said washer and thereby tightly'engage the coupling membei' attached to the valve casing, and further as the said cup washer is held practically stationary there is little or no wear on the said washer, and by reason thereof no water or d irt can pass between the washer and the coupling member in which it is housed, and in consequence no dirt or cuttings can injure the said washer or pass by the same and lodge between the dished face of the plunger and the ball valve.

In Figs. 5, 6 and 7, I havev shown a modified construction of my improved valve and in the said form the valve is a separate member 25, and provided with a non-circle lar'so'cket 26 to receive the pendent noncircular end 27 of the handle stem 28, which is held down in a tight connection with the valve by the cap devices and the disk washer. In this latter, or modified form, the nozzle end of thef'aucet oi' casing has a threaded connection with the body portion of the said casing. It will be noticed in the modified form, the ball valve 25 seats at the top, the bottom and at the opposite sides.

Figs. 10 and 11 show a still further modification ofthe construction of my faucet, and while the principle of assemblage ot' the other forms is adhered to, yet the body 1 is slightly altered to admit the provision of a side operated water faucet.

The easing 13 houses the plunger 5 which, in this instance, is vertically disposed and he casing is closed by a suitable cap 3 which, upon being screwed down, increases the tension in the spring (5, which being seated on the shoulder of the dished head 5() t'oi'ces the saidlatter part into close engagement with the ball valve 14 and this in turn tightly engages the seat 15, so that fluid may not escape around this latter connection. The ball valve has a duct 16 which when turned to the position shown affords a channel for the flow of the fluid.

Valve 14 has integrally formed templets 17 at its sides which by moving in suitably cored-out grooves in the body of' the faucet (see Fig. 11) keep the ball valve in the correct position and also afford a means by valve, a shouldered reduced portion and a stem having a threaded end; a coil spring seated on the said reduced portion, an elastic -washer mounted on the stem and engaging the coil spring to hold it up against the shoulder of the reduced portion of' the valve seat, and a clamp nut on the thread of the valve seat stem, said nut holding theelastic washer in place. n

2. A valve comprising a casing having an inlet and an outlet, a ball valve in the casing between the said inlet and l, outlet, a valve seat having a fluid passage movably mounted within the inlet end of the casing and having a shouldered portion and a stem having a threaded end, a coil spring mounted on the said shouldered portion that tends to orce the valve seat up against the ball valve, an elastic Washer including a cup shaped end that receives the impact of the outflowing fluid, the said washer being mounted on the valve seat stem and engag- 'ing the coil spring, and la lock nut on the valve stem for holding the parts of the valve seat -to their operative position.

3. A valve comprising a casing having an inlet and an outlet, a ball valve in the casing between the said inlet and outlet, a Yalve seat having a vfluid passage movably mounted within the inlet end of' the casing and having a shouldered portion and a stem having a threaded end, a coil spring mounted on the said shouldered portion that tends to force the valve seat up against the ball valve, an elastic washer including a cup shaped end that receives the impact of the outflowing fluid, the said 'washer being mounted on the valve seat stem and engag- -ing the coil spring, a lock nut on the valve stem for holding the parts of the valve seat to their operative position, the said stem of the valve Yseat extending beyond the inlet end of' the valve seat, and a pipe coupling that incases the said extended end and engages tlie inlet end of the valve casing.
